Awesome, Packed with a ton of information, watched 3 times to fully understand. Thank you 🙏
Your videos is always above and beyond on explaining that really shows your own understanding of the dynamics is really complete. Its better than a technical college class, thank you so much!

Thank you so much for all your videos. They are so informative. Thank you for taking the time to make them. I really appreciate it...
One of if not the most interesting video I've ever watched in my life 🤓
Learned a lot unexpectedly. You're video is really great and informative. Thanks for sharing
An excellent demonstration. Another benefit of neodymium in some applications is that their smaller size can lead to fewer reflections through the cone. Thanks again for such great work!
Ah damn, forgot to mention that lmao, 30 min vid some things slip by
@@Dakoustics No apologies necessary. A rigorous mathematical demonstration is always appreciated!
@@Dakoustics... Another thing for audio experts are the acoustics designs of speaker peripheral boxes. Some guys can't stand modern day speakers because they notice the sound acoustics differences in today's designs vs 1970-80s designs where speaker acoustic (the total wooden box and speaker system) sounded for stereos back then. Case in point: Why have modern TVs with HD require soundbars when TVs had great acoustical sound back in the 1970-80s? Back then listening to stereos and their designed speaker systems those amplifiers blew such rich sounds the ear couldn't differentiate a live vs record playing (or of FM radio station) performance. I still have the latest greatest RTR-IV 1982 from 50 Watts lower grade speakers outperforming many speaker designs today by an engineered speaker wooden shell also.
@@lawrencejelsma8118still well designed warm sounding 2 and 3 way speakers out there...just have to get them online.
@@lawrencejelsma8118the answer for tvs is pretty easy tbh. It's easy to get good sound from an old TV that was basically a big cube. Compared to flatscreens with maybe 0.05 cubic feet of space to spare for speakers.
Great info mate. Thanks for sharing. -Cheers
Brilliant. Really like how you went through the equations and math. It is hard to gain the same understanding from just reading a book.
Fantastic explanation, thank you!
Very informative video. I've read a lot of a B&C whitepapers and they recommend to get as much BL as possible regardless of any case. The one item worth exploring... apart from raw SPL is the apparent power required to generate said SPL: SPL vs. VA vs. frequency in WinISD, or Hornresp (which I prefer). Hornresp also gives an "Efficiency" plot in this regard derived from SPL vs. power. In the car audio game, a lot of the high-BL woofers will not model well on paper in a small box but when normalized watt for watt compared to low-BL offerings, they are far more capable, with the tradeoff that you need a similarly capably voltage source.
i love this video a lot, thank you! 😊😊
Good informative Video, thanks for sharing.
Brilliant the information is 100% correct. Thank You!
Big box, high BL, low inductance. Excellent sound quality (with Linkwitz transform). The curie temperature of N52UH grade neodymium magnets (used in high end subwoofers) is 180C/356F. Only the lowest all-purpose grades will demag at 80C.
All I can say is well put man Damn, you really know your stuff. Thank you. I learned a lot from this video.👍
That was awesome thank you.
Good video!
The neodymium magnets helped me a lot when I made panels so that everything could work properly like the passenger locker. Their shallow depth solves many problems. Thank you for this video master !!!
¿which is better, one large intonation port or two small intonation ports?
This is why I'm thinking 6 12-in subs with smaller ferrite magnets would be better than 218 in neos better heat dispersion and more surface area in 12 cubes
interesting! thanks for sharing your reseach.
The atari music is an annoying disdtraction though!
I guess to overcome curie heating issues Morel went hybrid using both neodymium and ferrite magnets together in their hybrid line of speakers.
Excuse me Mr. Dak, I bought some Neodymium magnets off of Wish, and when they arrived they turned out to be Pig Iron. Would this still be an effective magnet for use in my speaker system? They cost me $75000 and I really don't want to return them. Please help me.
Ah, an unfortunate problem far too many face. In order to turn your Yousless pig-iron into neodymium magnet, follow these simple steps:
1. A good nights sleep and hearty breakfast is a good way to start this day.
2. Place the pig-iron into the ceramic induction furnace, as prepared in step -3. Heat to a nice red glow. Barnaby Joyce face for reference.
3. Scrape off the SCUM. This might be carbon. Dispose of responsibly. You now might have pure iron idk
4. Assuming you ordered $75000 of Neodymium magnet, and the price is competitive, That's roughly 159.57446808 kg of neo magnet, aka your precious pig-iron. You must now add 58.92999028869 kg of elemental neodymium, which is found in the earth. A warning- it is also rare.
5. Add 38 cloves of Boron (which happens to be the 2.2kg required).
6. Make sure the broth is proper sunburnt Barnaby Joyce who's under ICAC investigation hot. Stir thoroughly.
7. Pour over your existing feeble speakers. If they are weak, they will ignite, and good riddance.
8. Wait for it to lightning. Your magnets are now magnets.
@@Dakoustics Thank you Mr. Dak. I have now been able to turn my pig iron into the neodymium magnets I so sorely needed. While the process caused my house to burn down and has turned me into a fugitive because it killed my neighbors in the induced lightning strike, I can now escape in style with my new speaker system. A shame I don't have any music to play, but I have connected up the speakers to the engine, and it is indeed very loud. Thanks again Mr. Dak

You will fail at stage 2.
Neomagnets are made from a fine powders mixture using powder metallurgy methods.
Hello im buying two dual 15" pa speakers with ferrite magnets can i expect great quality audio with these or will if differ compared to the other type of magnet and if i was to reload active speakers how would i go about it could you talk to me on email once i have them thank you im wondering what someones thoughts are on this they are vonyx speakers not sure if anyone has used them and what they think please talk im serious about audio quality i used to own a pair of mackie thump 15a's and they were great but im worried i may be going the wrong way they look very nice they are rated at 35hz for the low end and upto 20khz for the top end of the frequency response
What box program are you using?
WinISD, I'll put a link in the description
Look up subwoofer s that are made of such it’s amazing
Good
Strength per dollar is an interesting unit of measurement
That was awsome!
Tip: Magnets are hotter when you increasing the volume of bass. Once you get a distortion of subbass it's hot in a few minutes of listening some music.
Now I really want a Z series lol
Love my 818D but want neo
🔴 what is your advice on 2 subwoofers in a shared chamber vs separate chambers. have you ever made a video about it.
I wish I listened more in mathematics class right now.. 😳
Alnico the best!
Old school. A oldie but a goldie...
Alnico V was the hallmark of JBL loudspeakers and they still use them.
Nope. They was first.
But today they are far from the best.
My Pierce audio 21" sub ferrite magnets are rated to 360 Celsius!
Wow!
I was look for some professional dj driver for my dj set so this give imput in what to look for.
I have a pair of fi hc series 15s and one neo 4.11 18 and I can tell you this from experience the neo 4.11 18 is a cleaner sound but it gets warm faster than my hc 15s only a 500 watt difference

Hello sir which is stronger neodymium n35 vs y40 firrite magnet?
WOW! EXCELLENT!!!! You just helped me save $1000!!!!!😮😮😮😮😮😮 Neodymium isnt for me. I like it loud for LONG.
I heard that You can’t just replace a ferrite magnet with neodymium. It’s needs to be re-engineered and the neodymium requires more steel to generate a more powerful motor vs ferrite. More steel, more weight. So it’s not AS light as an optimistic example
Also ferrite is easy and cheap to magnetize. Neodymium is complicated and expensive
*@johnviera3884*
These rumors are not true.
The only difficulty is - not to pinch your fingers or break the magnets themselves during installation.
Need to use spacers and shims.
For me Xmax mostly depends on max THD. When you take a neo magnet and Ho frame with 3mm pole, you'll get a 1.5mm Xmax. Period. Otherwise this would be a tr.. driver. So, this layout is good for a highly efficient compression driver only.
PS ...and for a car "audio" of course. Then you can mound this driver on a suspension and get 2 in 1: a dancing car and a loud "boooo"
So use speaker with neodymium cars is really bad idea, it will easily get very hot in a car
If someone managed to demagnetize a magnet in a speaker due to overheating - then this speaker has an extremely crappy design.
